Andre,

Based upon 500v at 6mA with 0.1 spacing I would want to look for
alternatives.  What happens if the boards are well cleaned?  Do you
still see failures?  Are you locked into that capacitor?  We have
applications where we cut a slot between the component pins, then we
reduce the potential for surface tracking or creepage.

Subject: [TN] Arching or Current Leakage

We have a customer that has a portion of a circuit which randomly fails.
The circuit is a backlight driver (500volt 6mA). The output caps are
0.100
spacing of the terminals.  The process used is No-clean.  Can the
No-clean
contribute to failures of the circuit (ie promote arching or current
leakage across the body of the output caps). ???
